我把我的一些 note 貼上,你參考看看
Which switch is the root bridge for VLAN1?
# show spanning-tree vlan1 // This will show the MAC of the root bridge.
# show mac-address-table // To find out which port is connecting to the root bridge. Write down the port for later use.
# show cdp neighbor // This will give you the hostname of the connected port.
What mode is this switch running?
# show vtp status
關於第二個問題,就我所知是你要一台一台去 check
還有,如果沒實機操作的環境的話,可以試試 Packet Tracer 這套 cisco router / switch 模擬軟體,你可以用這軟體模擬一個 network layout ,然後可以在虛擬的 router or switch 上下指令,跟實機很接近的,可以用這套來學習
另外,我有上傳附件,這附件是 查 cisco 指令用的文件,挺實用的喔
另外,我覺得你需要一本書,關於你的問題,書上都有寫,這樣學得比較札實點
這本 CCNA 書 不錯
